These came in just a day late. Luckily I had a few SDHC cards in my Canon SX210 IS and Zoom H4n to fall back on. I was hoping these would arrive for the Music video shoot on the Canon 60D's, but we managed. So I haven't really tested these out yet, but i'll be shooting more fun stuff later this week to see the performance.

I use one of these cards in my 60d when we shoot commercials, only problem with huge cards like this for video is every once in a while the buffer gets lost and the camera will automatically stop. I've maybe had it happen 4-5 times, and I've probably been on 20-25 shoots. I prefer 8gb and 16gb cards for video because they seem to be more consistent, and if you are filming an event I think its a better idea to stick with the sandisk extreme because they've got so much head room.

That's strange that it's faster on your USB 3.0 port...
It shouldnt matter if its 2 or 3 - USB 2 provides up to 60 MB/s (480mbps)
more than enough for the transcends..
I bet your USB 3 ports are connected directly to the PCI-Express bus..could be the reason for the increased speed..

I concur, I have hit 20MB via my USB 3.0 port, 18MB via 2.0

Very untrue. I have two 16GB versions of these exact same cards. My tests show an average of 16-18 MB/s - I've hit 20 regularly - both reading and writing.
I <3 my transcends 🙂

Post authorThat's a false claim. There are numerous websites that have tested it against Sandisk. Sandisk is always the clear winner, but the Transcends can reach speeds of up to 18MB/s. It only needs to sustain a minimum of 10 MB/s to be rated a Class 10. If the minimum is 6 MB/s then it would be a Class 6.

I have heard that these cards only have class 10 read speed and not class 10 writing speed. Is this true?
